Justification:
Listed as Data Deficient because it is known only from the type specimen collected in 1901 and a record in 2013. The most recent observation is a site over 300 km away from the holotype record, therefore more comprehensive surveys may show the species to have a wider range.

This species is known only from the holotype location in Sarawak, Borneo, Malaysia. More recently it has been found during surveys of Labanan Research Forest located in Berau District, East Kalimantan at elevations between 125-275 m asl (Lestari et al. 2013).

It is threatened by habitat conversion due to agriculture and logging. One study demonstrated estimates of high forest loss and only small amounts of intact forest remaining in Sarawak (Bryan et al. 2013).
